Answer:
(5.5, -3.5)
Step-by-step explanation:
As you can see in the figure, the fourth vertex is (5.5, -3.5)
If you observe carefully the vertex given, you will see that there are two vertex with same coordinates in x axis:
- (-1.2, -3.5),
- (-1.2, 4.4),
And one vertex has other coordinate in x axis, it is: (5.5, 4.4)
To form a rectangle, you need a fourth vertex that will have same coordinate in x than (5.5, 4.4) and same coordinate in y axis as (-1.2, -3.5),
Then the fourth vertex coordinate is (5.5, -3.5)
It is an isosceles triangle which means that side BD=BC, The angles will be also equal i.e. Angle B= Angle C
<h3>Now,</h3>- Angle B = 4x+19
- Angle C = 2x+33
Now, We will find ∠D with the help of angle sum property of triangle
<em>The measure of angles are; 47°,47°,86° respectively</em><em>.</em><em>.</em><em>.</em>
